Viper: An Efficient Hybrid PMem-DRAM Key-Value Store

Summary: Viper is a hybrid PMem-DRAM KVS optimized for PMem-aware access patterns. A DRAM-based hash index and PMem-aware layout exploit DRAM random writes and PMem sequential writes, delivering 4–18x write speedups with full persistence and competitive gets.
